fable-thinking

mrgoonie/fable-thinking/skills/fable-thinking/SKILL.md

Reasoning protocol distilled from Claude Fable 5.1. Makes any model reason like Fable — evidence-grounded claims, multi-hypothesis diagnosis, concrete simulation, adversarial self-review, calibrated outcome-first delivery. Its never-skipped Floor check catches simple-looking trick questions models answer confidently wrong, and its Constraint Loop mechanically verifies hard output constraints (banned letters, exact counts, strict formats) that models otherwise rubber-stamp. Use for debugging, review, analysis, decisions, constrained writing, or any task where being right matters more than being fast. Domain playbooks apply it to long-horizon agentic work, sub-agent and runtime orchestration, coding and engineering standards, debugging to root cause, solution exploration, research, security, document vision, UI/UX, motion, engineering prose, skill use, token economy, and first-principles, sequential, and creative thinking, so smaller models reach Fable-grade output at a smaller token budget.
